The gorgeous 90210 actress sizzled in a tiny blue and purple bikini in her latest Instagram pic. In the sexy photo, the brunette lounges poolside with friends and gives us all a perfect glimpse of her rock-hard abs and side boob.

Back in November, the beauty showed off her flawless figure in a thong bikini from the line. "Lovin' my @vitaminaswim bikinis! Thank you so much @yfraynd xo," she wrote.

She posted the snapshot just weeks after her breakup from Scottish rugby player Thom Evans. The good-looking pair, who dated for seven months, split in October after struggling to maintain their long-distance relationship.

But single life seems to be treating her well. Lowndes will star in The Prince later this year with Bruce Willis and John Cusack.
